The present invention relates to garage door locks and more particularly to a novel escutcheon assembly for use on a garage door or other closure requiring both a rotatable spindle to operate a bolt and a tail piece for a tumbler lock operating a latch mechanism for the bolt.

An important object of the present invention is the provision of a novel escutcheon assembly on the exterior of the door which houses a tumbler or rim lock therein having a rearwardly extending tail piece, and a rotatable handle having a rearwardly extending spindle. The handle and the face of the tumbler or rim lock having the keyway therein are exposed at the front or face of the escutcheon. A bearing for the handle and its associated spindle provides for a limited arc of rotation of the handle and spindle in either a right-hand or left-hand movement.

Another important object of the present invention is the provision of a novel escutcheon assembly for a closure lock having a housing for the tumbler or rim lock extending rearwardly of the escutcheon; the housing having an open rear end. A spring clip is secured to the lock housing when the lock is inserted therein to retain the lock within the housing in operative position. The spring clip includes a pair of spring arms with inturned ends engaging in openings in the sides of the housing and an inwardly bowed connecting portion extending across the rear open end of the housing, with the inwardly bowed portion engaging the rear end of the lock and retaining the lock in operative position.

Further objects are to provide a construction of maximum simplicity, efiiciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

In the drawing:

FIGURE 1 is a front elevational view of a novel escutcheon assembly housing and mounting a cylinder lock and a handle adapted to be employed with a garage door lock assembly.

FIG. 2 is a side elevational view of the escutcheon of FIG. 1.

FIG. 3 is a top plan view of the escutcheon assembly of FIGS. 1 and 2 showing the retaining clip for the cylinder lock and the key inserted into the lock.

3,452,564 Patented July 1, 1969 FIG. 4 is a rear elevational view of the escutcheon assembly of FIGS. 1, 2 and 3 with the handle removed.

Referring more particularly to the drawing in which is disclosed an illustrative embodiment of the present invention, FIG. 1 discloses an escutcheon assembly including an elongated escutcheon 10 provided with an opening 11 adapted to receive suitable securing means to attach the escutcheon to a door (not shown). The escutcheon assembly provides a housing or enclosure 12 extending rearwardly from the escutcheon 10 having a central opening 13 extending therethrough with an upwardly extending slot 14. The face of the escutcheon includes an opening 15 communicating with opening 13 to provide the key 17 access to the keyway 16 in a cylinder lock 18. Any standard cylinder lock having the upward extension 19 for the tumblers can be used in this housing.

A retaining clip 20 has an approximate U-shape with generally parallel arms 21 having inturned ends 22 and the connecting member between the arms 21 includes a central inwardly bowed portion 23. Openings 24 are formed on each side of the housing 12 adjacent the slot 14. The cylinder lock 18 is inserted into the housing 12 after which its retaining clip 19 is affixed with the ends 22 entering openings 24 and the bowed portion 23 engaging the rear surface 25 of the lock; the lock including an actuating tail piece 26 for the garage door or other lock.

The handle assembly 27 with its spindle 28 is rotatably mounted in a bearing 29 in the escutcheon 10, which bearing extends rearwardly of the escutcheon terminating in a surface 31 having a pair of oppositely disposed, arcuate camming slots or depressions 32 (FIG. 4). The handle assembly 27 includes a handle 33 having a rearwardly extending cylindrical extension 34 conformably fitting within the bearing 29. The extension terminates in an opening to receive the spindle 28 and includes a pair of radial openings 35 aligned with an arcuate slot 32 and spaced approximately A spirol pin 36 is inserted into one of the openings 35 and serves the dual function of retaining the handle assembly 27 in the escutcheon and limiting rotational movement of the handle 33. The pin 36 is shown in FIG. 4 for a lefthand arrangement in solid lines and may be shifted to the alternate opening 35 in which the pin is shown in dotted lines to adapt the unit for right-hand operation.

Although the novel escutcheon 10 is shown and described as being advantageously applicable to a garage door lock, it is not my desire or intent to unnecessarily limit the scope or the utility of the improved features by virtue of this limited showing.

Having thus described my invention, I claim:

1. An escutcheon assembly adapted for a garage door lock assembly comprising an elongated escutcheon having a pair of spaced openings therein, a housing extending rearwardly of the escutcheon and aligned with one of said openings, a cylinder lock located in said housing, a retaining clip attached to said housing and engaging said cylinder lock to retain the lock in the housing, said clip including a pair of generally parallel arms terminating in inwardly extending ends engaging the housing, and an inwardly bowed portion joining the arms, said bowed portion engaging the end of the cylinder lock, a bearing defining the other said opening and extending rearwardly of the escutcheon, a handle mounted on said escutcheon and having a cylindrical extension passing through said bearing, and means retaining the handle in the escutcheon.

2. An escutcheon assembly adapted for a garage door lock assembly comprising an elongated escutcheon having a pair of spaced openings therein, a housing extending rearwardly of the escutcheon and aligned with one of said openings, a cylinder lock located in said housing, a re- 3 taining clip attached to said housing and engaging said cylinder lock to retain the lock in the housing, a bearing defining the other of said openings and extending rearwardly of the escutcheon, a handle mounted on said escutcheon and having a cylindrical extension passing through said bearing, and means retaining the handle in the escutcheon including said bearing terminating rear- Wardly of the escutcheon in an end surface having a pair of oppositely disposed arcuate slots therein, said slots extending over an arc of approximately 90 and a pin connected to said handle and moving in one of the slots to limit rotation of the handle.

3. An operating assembly for a garage door lock assembly as set forth in claim 1, in which a tail piece is secured to and extends rearwardly of said cylinder lock and a spindle is secured to and extends rearwardly of the handle for cooperation with the door lock as sembly.

4. An operating assembly for a garage door lock 4 assembly as set forth in claim 1, in which said housing and said bearing are integral with said escutcheon.
